Hello, I am Erik the programmer of YouDJ. I am an audio engineer, programming YouDJ for 10 years as a passion project! I don't have any team or cost, that's why I make this DJ app ENTIRELY FREE! My mission is to create the most FUN and EASY dj app, so even my mother can be a DJ! Therefore, YouDJ is NOT the most complete DJ app but offers the must-have, high quality, DJ tools. It is still usable by advanced DJs but if you need more tools (MIDI controllers...), use a pro DJ app. But again, it is very good for a free app ;). Included DJ tools : 16 sound effects, sampler with 80 samples, vinyl scratching, auto beat synchronisation, keylock, loops, automix, hotcues... To finish, you don't need to have music on your device, the app is preloaded with great music from talented artists I personally know. Support them please by following them on social medias. You can also play MP3 files stored on your device. Important : No DJ app (including YouDJ) will work with Apple Music / Spotify / Youtube Music because these are closed platforms and all their songs are encrypted with DRM. Also there is no legal way to mix popular music without paying on mobile, so don't ask me why there is no Justin Bieber in the demo playlists!! ;) YouDJ is available on all desktop and mobile platforms. You should definitely try at least the computer version too (you.dj). Hoping you will love the app and be prepared to waste lot of time ;) If you want to thank me for all my time I put in this app for no money, you can give me a good review, it helps me a lot, thanks! ---------- HOW TO MIX What you got is a traditional DJ setup : 2 turntables and a mixer. Your mission is to play simultaneously two songs on each turntable and to use the mixer to mix them together. To spice up your mix, you can use effects such as the loops, the fx pads, the eq, the scratch, the sampler, the hot cues... ---------- Again, BIG THANKS TO YOU for loving YouDJ, it motivates me to continue the project, Have fun with YouDJ and take care :) Erik
